Sub-nanosecond polarization switching with anomalous kinetics in vdW ferroelectric WTe2 [PDF]

Nature Communications
Recently discovered “sliding ferroelectrics” exhibit distinct polarization origin and switching mechanism compared to conventional ferroelectric materials. However, a clear understanding of the polarization switching kinetics remains lacking.

A ferroelectric memristor [PDF]

Nature Materials, 2012
Memristors are continuously tunable resistors that emulate synapses. Conceptualized in the 1970s, they traditionally operate by voltage-induced displacements of matter, but the mechanism remains controversial. Purely electronic memristors have recently emerged based on well-established physical phenomena with albeit modest resistance changes.

Solvent Selective Effect Occurs in Iodinated Adamantanone Ferroelectrics

Advanced Science, 2022
Organic ferroelectrics, as a type of crystalline compound, are generally solution processing. However, for most crystalline compounds, the changing of solvent would not influence the crystalline phase, let alone their physical performance.
